react-hook-form 作者在这里。Antd Input 组件并没有真正公开 inner ref，因此您必须在 onChangeregister期间useEffect更新值，例如：

const { register, setValue } = useForm();

useEffect(() => {
  register({ name: 'yourField' }, { required: true });
}, [])

<Input name="yourField" onChange={(e) => setValue('yourField', e.target.value)}

我已经构建了一个包装组件来使 antd 组件集成更容易：https : //github.com/react-hook-form/react-hook-form-input

import React from 'react';
import useForm from 'react-hook-form';
import { RHFInput } from 'react-hook-form-input';
import Select from 'react-select';

const options = [
  { value: 'chocolate', label: 'Chocolate' },
  { value: 'strawberry', label: 'Strawberry' },
  { value: 'vanilla', label: 'Vanilla' },
];

function App() {
  const { handleSubmit, register, setValue, reset } = useForm();

  return (
    <form onSubmit={handleSubmit(data => console.log(data))}>
      <RHFInput
        as={<Select options={options} />}
        rules={{ required: true }}
        name="reactSelect"
        register={register}
        setValue={setValue}
      />
      <button
        type="button"
        onClick={() => {
          reset({
            reactSelect: '',
          });
        }}
      >
        Reset Form
      </button>
      <button>submit</button>
    </form>
  );
}

这是我的工作方法：

const Example = () => {

 const { control, handleSubmit, errors } = useForm()

  const onSubmit = data => console.log(data)
  console.log(errors)

  return (
    <Form onSubmit={handleSubmit(onSubmit)}>
      <Controller
        name="email"
        control={control}
        rules={{ required: "Please enter your email address" }}
        as={
          <Form.Item
            label="name"
            validateStatus={errors.email && "error"}
            help={errors.email && errors.email.message}
          >
            <Input />
          </Form.Item>
        }
      />
      <Button htmlType="submit">Submit</Button>
    </Form>
  )
}

在编写这样的代码时：

<Input
  name="subtitle"
  placeholder="Add a subtitle"
  ref={register({ required: true })}
/>

您假设Input引用绑定到input，但事实并非如此。

实际上，您需要将其绑定到inputRef.input.

您可以使用下一个代码进行检查：

const App = () => {
  const inputRef = useRef();
  const inputRefHtml = useRef();

  useEffect(() => {
    console.log(inputRef.current);
    console.log(inputRefHtml.current);
  });

  return (
    <FlexBox>
      <Input ref={inputRef} />
      <input ref={inputRefHtml} />
    </FlexBox>
  );
};

# Logs
Input {props: Object, context: Object, refs: Object, updater: Object, saveClearableInput: function ()…}

<input></input>

注意这antd是一个完整的 UI 库（使用 3rd 方“助手”应该“闯红灯”），特别是Form实现了一个验证器，您可以在 docs 中看到各种示例。

在 Ant Design v4.x + react-hook-form v6.x 中。我们可以照常实施

import { useForm, Controller, SubmitHandler } from 'react-hook-form';
import * as yup from 'yup';
import { yupResolver } from '@hookform/resolvers/yup';

import { useIntl } from 'react-intl';
import { Input, Button, Form } from 'antd';

const SignInSchema = yup.object().shape({
  email: yup.string().email().required(),
  password: yup.string().required('required').min(6, 'passwordMin'),
});

interface PropTypes {
  defaultValues?: {
    email: string;
    password: string;
  };
  handleFormSubmit: SubmitHandler<{ email: string; password: string }>;
}

function SignInForm({ defaultValues, handleFormSubmit }: PropTypes) {
  const intl = useIntl();
  const { handleSubmit, control, errors } = useForm({
    defaultValues,
    resolver: yupResolver(SignInSchema),
  });

  return (
    <Form onFinish={handleSubmit(handleFormSubmit)}>
      <Form.Item
        validateStatus={errors && errors['email'] ? 'error' : ''}
        help={errors.email?.message}
      >
        <Controller
          as={Input}
          name="email"
          autoComplete="email"
          control={control}
          placeholder={intl.formatMessage({ id: 'AUTH_INPUT_EMAIL' })}
        />
      </Form.Item>
      <Form.Item
        validateStatus={errors && errors['password'] ? 'error' : ''}
        help={errors.password?.message}
      >
        <Controller
          as={Input}
          name="password"
          type="password"
          control={control}
          autoComplete="new-password"
          defaultValue=""
          placeholder={intl.formatMessage({ id: 'AUTH_INPUT_PASSWORD' })}
        />
      </Form.Item>

      <Button type="primary" htmlType="submit">
        {intl.formatMessage({ id: 'SIGN_IN_SUBMIT_BUTTON' })}
      </Button>
    </Form>
  );
}

export default SignInForm;
